A Los Angeles megamansion once expected to list for $500 million has gone into receivership after the owner defaulted on more than $165 million in loans and debt, according to court filings. The 105,000-square-foot Bel Air estate, known as “The One,” was placed into receivership and is expected to be relisted at a lower price. The receivership marks a stunning reversal for “The One” and its flashy developer, Nile Niami, who often touted the property as his “life mission.” $Household & Personal Products (LIST2003.US)$ $S&P 500 Index (.SPX.US)$
